WEIGHTED BALL FOR NON-REFILLABLE BOTTLES.

SPECIFICATION forming part of Letters Patent No. 794,830, dated July 18, 1905.

Application filed August 10, 1904. Serial No. 220,219.

To all whom it may concern.-

Be it known that 1, JOHN S. WRIGHT, a citizen of the United States, residing at Duxbury, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Weighted Balls for Non-Refillable Bottles, of which the following is a specification.

This invention relates to a ball adapted to be used as a valve for non-refillable bottles,

the object of the invention being to provide a ball which, together with a suitable seat, will seal a bottle so that liquid cannot be introduced into said bottle even under a vacuum.

The invention consists of a ball adapted to be used as a valve for non-refillable bottles, said ball provided witha recess and a weight in said recess of greater specific gravity than the body of said ball.

The invention again consists in the combination and arrangement of parts set forth in the following specification, and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a vertical central section of a bottle with my improved ball therein. Fig. 2 is a central section of said ball. Fig. 3 is a section of said weighted ball,illustrating its position with relation to the surface of a liquid in which it is immersed. Fig. & is a central section of a modified form of my improved ball. Fig. 5 illustrates another modified form of my invention.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 8 is a bottle of any desirable style. '9 is a ball constructed in accordance with my invention. located in the neck 11 of said bottle, and 12 is a stop also located in the neck 11 of said bottle to prevent the ball from being tam pered with and also to prevent said ball from being removed from the bottleneck. The stop 12 and valve-seat 10 may be of any desirable construction without departing from the spirit of this invention.

10 is a valve-seat In Fig. 2 a cork ball 9 is illustrated with recesses 13 therein containing weights 14:, said weights being of greater specific gravity than the main body of the ball.

In Fig. 4 another form of ball 9 is illustrated in which a recess 13' is provided containing a weight 14:, said weight being introduced into said ball through a passage 15, which is subsequently filled by a plug 16.

In Fig. 5 a hollow ball 9 is illustrated, containing a globule of mercury 14 which serves as a weight.

In Fig. 3 the full line a illustrates the surface of the water with relation to the ball 9 when said ball is weighted as illustrated. The dotted line a illustrates the relative position of the surface of the water to the same ball without the weights. It has been found by practical experiment that a ball constructed as hereinbefore described, in connection with a valve-seat, forms a perfect means for sealing a bottle so that liquid cannot be introduced into the interior thereof, and when a vacuum is formed in an empty bottle. and said bottle then connected with a supply of liquid even under these conditions the liquid will not enter the interior of the bottle, whereas if the same ball without the weights is used and the bottle subjected to a vacuum test liquid will enter the interior of the bottle, the explanation of this result being that when the bottle is inverted, having previously had the air exhausted from the interior thereof and the bottle connected to a supply of liquid, if the ball is not weighted as the liquid rushes up through the neck the ball will be forced against the seat and immediately bounce backwardly therefrom and allow liquid to enter the bottle by repeated movements of the ball of this nature before the ball settles against the seat and closes the same against entrance of the liquid, and this is especially the case where cork is used for the main body of the ball; but where the body of the ball is of cork and is weighted it comesto a bearing upon the valveseat 10 under the conditions hereinbefore set forth and remains in that position, effectually ball-valve provided with a recess, and a Weight sealing the bottle against the introduction of in said recess of greater specific gravity than liquid to the interior thereof. the body of said ball-valve.

Having thus described my invention, what In testimony whereof I have hereunto set 5 I claim, and desire by Letters Patentto secure, my hand in presence of two subscribing wit- 5 1snesses.
